摘　　要：研究机场人流优化疏散问题,由于机场内人流和滞留旅客量大,进行行人行为建模得出行人活动规律,是进行人员疏散、维护公共安全的基础。针对机场的空间特点,研究人员采用势能场方法对行人行为建模,通过目的地和障碍物等对行人的影响来确定行人的总势能。同时采用精细网格模型对特定区域进行行人行为仿真。仿真结果表明,在变截面空间的运动中,行人在低密度情况下可不受截面变化影响。对于高密度情况,行人会受到相互干扰,以被迫改变自己的运动轨迹。研究给出了相关行人轨迹,为疏散提供参考。Researching the pedestrian modeling which summarizes the discipline of pedestrian activity.It is the foundation of pedestrian evacuation and public safety.The model of pedestrian behavior in airport based on potential field is proposed.The pedestrian potential energy is determined by the destination,obstacles and other pedestrians.Small grid model is used to simulate the pedestrian behavior in specific region.The results of simulation indicate that the pedestrian behavior with low flow density is not affected by the changing section.However,for the case of high flow density,the pedestrian behavior trace will change by mutual interference.The pedestrian path and related data are presented.
